To all whom t may concern.- A

Beit known that I,.FREEB0RN F. RAYMOND,

2d, of Newton, in the county of Middlesex and State of Massachusetts, acitizen of the United States, have invented a new and usefulImprovenient in the Process of Attaching Heels to the Soles of Boots orShoes, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings,forming a part of thisspecification, in explaining its nature.

The invention relates to a process of attaching heels to the soles ofboots and shoes, comprising the following steps: first, the attachmentof theheel-blank to the sole of a boot or shoe by a gang or group ofattachingnails simultaneously driven, and so as to leave their headsprojecting from the exposed surface of the blank; second, in applying atop lift which has previously been cut to .an exact or finished shape tothe heel-blank and the extending butts of the attaching-nails; third, informing simultaneously in the heel a line of holes placed closelytogether and close to the edge of the top lift, and inclined inward fromthe surface of the top lift; fourth, in driving a gang or Vgroup ofsmall nails into said holes,which shall becaused bythe inclination ofsaid holes to be turned inward as they are driven, but which do notextend through the heel-blank; fifth, in the subsequent trimming orfinishing of the attached heel.

This method of attaching a heel permits a line of nails to be drivenvery closely to the edge of the top lift, yet allows the heel to beundercut in trimming, and I am thereby enabled to obtain a veryfinely-iinishedheel, and to apply close nailing to ladies wear and toundercut heels generally. g

Referring to the drawings, Figure l is a section to illustrate theheel-blank attached and the attaching-nails thereof. Fig. 2 is aplan vewof the attached heel-blank. Fig. 3 shows the attached heel-blank and thefinished top lift in position over it before it is applied. Fig. 4represents the finished topflift as attached to the heel-blank. Fig. 5is a section showing the gang or group of holes formed close to the edgeof the finished top lift and extending downwardly and inwardly into thenished blank. Fig. 6 is a plan View to show tne relation of the holes tothe edge of the finheel-blank-attaching nails.

Fig. 9 is a section toshow the relation of the exterior gang of nails to an undercut trimmededge of a heel. Fig. l0 is a view in perspective of a complete heel.Fig. 11 is a view, partly in vertical section and partly in elevation,of mechanism adapted to carry my method into effect. Fig. 12 is a Iplanview showing a templet and nail-holder for use in practicing my method.

In the drawings, A is the sole of the boot or shoe.

' a is the heel-blank.- It is placed upon the heel end of the sole andis compressed thereon. It is secured thereto by the attaching-nails a',which are driven through the blank into the sole of the boot or shoewith their ends or heads a2 left projecting from theexposed surface ofthe heel-blank. But few or" these attaching-nails are used, only asuiicient nur nberlto properly secure the heel-blank to the sole of theboot or shoe. They are simultaneously driven, and the driving mechanismfor compressing the blank and driving these nails may be of such acharacter that the same arrangement or group of nails maybe used forattaching blanks of a great variety of sizes in View of the outer andmore accurate nailing referred to.

B is the top lift. It is cut or died lto exact shape, and is applied tothe heel-blank so as to bring it central in relation to the heel-seat ofthe boot or shoe. This stage of the process is represented in Fig. 4..There is then formed in the heel, close to the edge of the top lift, agang cr group of inclined holes, b. These holes are small in size andare short, not extending much beyond the second or third lift of theheel from the top lift, and they are all inclined inward to a greater orless extent, according to the finish of the heel edge-that is, accordingto the extent ofthe under-cut thereof.

The nails b which are used are preferably round, although I do notconfine myself to that especial shape, and they may or may not beheaded.` They are Very small compared with the usual attaching-nails,and are not driven entirely through the heel into the sole,but aredriven a little greater distance than the depthl of the awl-holes. Thisproduces a line of vvery ICO" small nails having their heads exposed andplaced closely to the edge of the finished top lift, and in regularorder in relation thereto, so that the edge of the top lift and of thetwo or three lifts next in order are held rmly secured to each other,and checking is practically impossible, while a very neat and tin ishedappearance is provided the heel, as well as an exposed Wearing-surfaceof the metal.

By driving thenails as indicated-namely, in a gang or group' of inclinedholesthey can be placed very closely to the edge, and the heelsubsequently trimmed straight and even undercut to a considerable extentwithout cxposing the shanks of the nails; and this is of very materialadvantage, as it enables me to nail ladies, misses, and childrens Work,as well as the iiner grades of mens work.

Of course in some instances the top lift can be attached to theheel-blank with the attaching-nails to the soles of the boot orshoe, inwhich case the attaching nails are driven through the top lift.

I would say, further, that the attaching-nails may be driven flush withthe surface of the heel-blank instead of being left projecting, asrepresented in Figs. 1, 3, and 4. i

In practicing this method I prefer to use a last or worksupport, C, atemplet, D, having the line of large holes d, through which theattaching-nails ct are driven, and a line of small holes, d', throughwhich the outer line of small nails is driven. Theseholes may beiuclined from the upper surface of the templet inward, but I prefer touse awls having long beveled eccentric points arranged in their holderto form holes in the heel-blank inclined inward.

E is the nail-holder. It has two lines of holes, e e'. The line of holese receives the large attaching-nails, and the line of holes e thesmaller nails.

F is the gang of awls used for forming holes in the heel-blank for theattaching-nails.

F is the gang or group of drivers for driving the attaching-nails.

F2 is the toplift holder.

F3 is the gang of awls for forming the inclined holes in the top liftand heel-blank.

F is the gang of drivers for driving the outer line of small nails...

F6 isa spanker for leveling the tread or surface of the heel after thesmall nails have been driven. l

In practicing the method the heel-blank is placed upon the boot or shoe,and it is pricked for the reception of the attaehingnails, which arethen fed by the nail-holder and driven. The top lift is then spanked,the heel pricked by the short awls, the shorter nails fedas a gang orgroup and driven, and, if desired, the complete heel spanked or leveled.

Having thus fully described myinvention, I claim and desire to secure byLetters Patent of the United States- The process of attachingheel-blanks and top lifts to vthe soles of boots and shoes, comprising,first, the attachment of the heel-blank to the soles of boots and shoesby attachingnails driven through it into the soles of a boot or shoe;second, in locating or centering the finished top lift upon theheel-blank in proper relation to the heel-seat of the boot or shoe;third, in simultaneously forming in the heel a gang of small holesplaced close to each other clined inward or frm the edge of the heel;fourth,- in simultaneously driving into said inclined holes a gang orgroup of small nails an inclined direction as they aredrivenfsubstantially as and for the purposes described.
